Graphical improvements on 4.0

Hello!

First of all, I want to say that the new visuals for the 4.0 looks amazing and I absolutely love how the FX animations are going on.

I would like to talk about something that is simple and could dramaticaly improve the realism on the usage of spells which involve light:
When a character casts a spell, (let's figure that this spell is a fireball) it should illuminate the environment and the nearby objects and characters in a radius of two meter from its center with a red color. Now, the spells lights are not merging with the envirnoment.

I think it could be a huge improvement about achieving more believable visuals.

Thank you!!
